To all whom it may concern:

Be it known that I,--'THOMAS DANIEH' STAGG, subject of the Kingbof GreatBritainand Ireland; residing at Villa" Rustica,

Herne Hill, London, S. E; Englande-have" invented new and useful Improvements: in and Relating to the-Wheels of Vehicles Driving-Pulleys, and-Hie like,- of whichthe following is a specification. I

My invention relates to wheels-for vehi cles,- driving pulleys and the like andlias for its object the construction ofsuch devices whereby greater strength; greater durabil ity, simpler'construction and ease of r'epair can be obtained compared-with known de-' vices.

According to this invention the na ve'or hub of the wheel has formed on" its *face or on both faces a series of semi' c'ircular re''- cesses the walls of which-extend laterallymore or less in the same direction as the axis. Into each recess isdisposedaspoke of U formation the outer ends of which en gage with the felly I of the wheel. The walls of the recess and the portion of the spoke engaging therewith may be of slightly inner edge of each spoke lies adjacent to a plane passing through the center of the" wheel. i I

The felly of the wheel is'-provided"with a tire of any. suitable constructiom Inorder to provide means other than the tire for binding the parts of the wheel tegether a circular ring formed in segments with con necting pieces is passed through the center portion of the spokes, andtightening bolts are attached to the'ring and passup through the felly; the nuts on the outside thereof when tightened down draw the felly toward the center of the wheel. Or equivalently the tightenin bolts may be attached to a flange on the hu bQ If necessary bolts may be arranged through the spokes, side plates and the hub in order to assist in taking the driving ef- 5 fort.

tiona very large embeddingsurface is provided' on the spokes at their'inner end where theyabutag' ainsttlle hub order to take thepressure inward in a radial "direction.

In order that the" invention maybe the better'nnderstood will now proceed to describe the "same in relation to 'the ac'comanyingdrawing, reference being had to the letters andfigures marked thereon; Like lette'rs'---refer to like parts in the various figures. in which t p Figurel is zit-side view are wheel-with two sets-of spokes constructed in accordance with this invention, one side plate being broken' away to show two spokes in their recess'es. i

Fig. 2 is 'a transverse section of-the same.

Fig: 3"i's aside'vi'ew of one of the spokes.-

Fig; 4 isa view of same at right angles to" that? in Fig. 3. 1

Fig; 5--isa' view showing the felly attached to the hub by tension bolts.

Fig. 6is;a=part'\' iew of'a wheel'with one set 1 of spokesconstructed according to the invention-with aset of intermediate ordinary spokes. v

In'Fi'gs'. I and 2' the hub a has a'central boss I) and centrally disposed flange 0 thereon. Oneachface of the'flange' 0 are disposed walls-d d of semi circular formation extending outward and arranged to form recesses" into-which the spokes e of wood "or-other e'qi'iiv'alentlyresilient material are for'ced'unde'r pressure. The walls 05 d are placed slightly oblique to one another so as to make the recess slightly taper to insure the spoke 6' being janirned tightly therein. Each spoke e is of U"s'l rape-made prefera-bly of 'woo'db'ent fromthe straight under heavsothat the fibers of'the wood run parallel'td the sides of the spoke a. At each outerendof'the spoke e is formed aten'on j which is inserted into a hole in the felly h,

the'te'non' f. being cutaway at one side as shown in Fig. 4 to enable the tenon f to be inserted iiitoits'hole g. "The felly h is pref erabiy made of wood in sections and when all the sections of the felly h and the spokes e are engaged with one another and the circular part of the spokes have been forced into the recesses on the hub a the whole structure is consolidated by a bonding tire i forced or shrunk on to the felly h.

011 each side of the hub a is arranged a side plate 72 and through the plates 72 and the hub a are a series of bolts j which hold the spokes e in their recesses and consolidate the hub portion of the wheel. The bolts j preferably pass through the body of the spokes e to prevent them moving in the recesses in a circular direction, or equivalently other locking means may be provided. For vexample'rib's omay be formed on the wall d to engage channels across thespoke or the spokes may be formed in two parts, the division being preferably madeinthecenter of the curved portion and a transverse wall may be provided across the recess against which'the, endsof the curved portion can abut. Any driving or retarding action on the spokes isexerted in a tangential direction from'the hub to the felly or vice versa. The plates is are furnished on their inner faces with projecting fences 4' which fit into and engage the walls d and d so that the strains transmittedby the bolts j are uniformly distributedto the hub a.

In Fig. 5 the sections of the felly h are anchored tothe hub a byuscrewed tension the hookedend 9, shown in dotted lines, of the rod Z can be engaged so as to be anchored] thereto.

In Fig. 6 a; partwheel is shownhaving only one set of spokes vc-constructed and fixed in accordance with this invention and i in addition thereto an ordinary spoke c is mounted in a pocket e in the hub a between each pair of spokes c to support the felly hand form increased driving means when the wheel is used for driving or braking purposes.

I claim I I 1. A wheel structure of the compression spoke typeconsisting of 'a hub element having a series of curved recesses arranged around same, a series of spoke elements of wood of substantially U shape firmly 1nsert-,

ed into said recesses, a felly into which the outer ends ofthe spokes are engaged, re-

cesses in said felly for receiving theouter ends of said spokes lateral supporting means for holclmg said spokes 1n the recesses 1n the hub element and bonding means disposed about said felly for forcing the felly against the ends of the spokes and the curved portion of the spokes into the hub recesses and thus consolidating the whole structure, substantially as described.

21A wheel structure of the compression spoke type consisting of a hub element having a series :of. curved recesses arranged around same, a series of spoke elements of wood of substantially U-shape firmly insertedinto said-recesses, a felly into which the outer ends of the spokes are engaged, recesses in said felly for receiving the outer ends of said spokes, lateral supporting means for holding said spokes in the recesses in the hub element, bonding means disposed about said; felly for forcing the felly against the ends of the spokes and the curved portion of the spokes into the hub recesses and thus consolidating the wholestructure, and lock- 7 mg means. between said spokes and the hub,

said locking means being transversely disposed relative to the plane of the spokes.

8. A wheelstructure of the compression spoke type consisting of a hub element having a series of curved recesses arranged around same, a series of spoke elements of wood of substantially U-shape firmly inserted into I said recesses, a felly into which the outer ends, of the spokes are engaged, recesses in said felly for receiving the outer ends of said spokes, lateral supporting means for holding said spokes in the recesses in the hub element, bonding means disposed about said felly for forcing the felly against the ends of the spokes and the curved portion of the spokes into 'the'hub recesses and thus consolidating the whole structure, and a plate-for holding the spokes in place in the hub adapted to interlock with said hub so as to transmit the driving and braking effort through ,same uniformly around said hub. v y In testimony whereof I have signed my name to this, specification in the presence of two subscribing witnesses.
